Step 1 – connect Temperature sensor with Arduino.
Connect sensor VCC pin to Arduino 5V port, GND pin to Arduino GND port and VOUT pin to Arduino A5 port.
see following graph:

Step 2Download tempsensor.ino sketch and load it into Arduino.

open the serial monitor window in Arduino IDE upright corner, you will see temperatures as following pictures:

TMP36- 5 Sensor- TEST

TMP36 Datesheet downlink :

If you want use 5pcs tmp36 sensor to test  surrounding enviroment temperature, you could follow these steps.
